Hey all. I posted these two question in the big chill section, but haven't gotten a response. Thought maybe somebody looking in this section would have a better chance of know the answers. Question 1-Where can I get a new filter for the a/c coils in the trunk. Mine is trashed. If I can't get a new one, any tips on making a new one? Question 2-How many pounds of refrigerant do I need to charge the system? I'm transferring the whole system from one my parts car to the driver, so obviously it's completely empty. Thanks
Filter? I dunno. You'll probably have to fab something up. As far as the charge level, if you have a receiver-dryer with a window, you can monitor that after a thorough evacuation and recharge. No bubbles means a full charge. Not being familiar with that old a type of system, I'd recommend approaching that "no bubbles" business with some healthy caution. Put a gauge in the AC outlet and watch that. Be sure that the high side pressure doesn't get too far over, say, 250 PSI. I've seen them go as high as 400 PSI if it's a hot day. If it gets up there, it isn't necessarily overcharged, it's probably too hot. Since you will be sitting still, put a big high-flow fan in front of the radiator if it starts to heat up. Or, shut it down, let it cool and pick up again where you left off.
What type of filter are you referring to ? Is it an inline ? Anyways have you tried Old Air Products ? They deal in some older stuff.
By filter, do you mean the receiver-dryer? About 10" tall and 2" across, with a glass window under a plastic cap? Bulldog, you need to trade up to that 2-90 model.
I haven't looked at Old Air Products much, I will go through their website some more. The filter just sits on top of the coils like in the picture below. It just catches crap that comes in from the outside vents, or from inside the car, where ever I have it set to draw air from. It's only 1/2" thick. Here are some more pictures of the filter: Top Bottom Side(ish) View
That looks exactly like the vent-a-hood filters that go over your kitchen range to catch grease. It is a stainless mesh and possibly a poly fabric in between.
I have been looking at range filters for quite a while but never found one the same size. What I might do is try taking mine apart, buying a range filter, and then somehow putting it in my frame and hoping it works. I've also thought about how to clean it. The mesh is fairly fragile (can't scrub the crud off) so I'm not sure how to go about cleaning it. Soaking it in something would be the only way i can think off, but I don't think water would cut it. Maybe I'll try filling a 5 gallon bucket full of warm water and dish soap and let it soak for day and maybe it will rinse off.
Just what I was thinking. I'll bet Tom T is right though, I'm sure that you can clean it with a solvent like simple green.
It looks like what our refridgerators have at the restaurant. That's what we do. A light spray of hot water. like from a kitchen sink sprayer.......... that, would be worth a try. Maybe, the best solution.:TU:
Count on at least 5 pounds. I have done many of these factory 55 systems, both as rebuild and service existing installation and as change over. I have a writeup on my website on compressor seals and should be able to answer most questions and give some tips if needed. You are free to contact me, but if there is interest, I like to keep it on the forum so others can benefit....looking forward to helping. Willie
I just pulled all the copper lines off the parts car to clean them and reinstall on my car. What is that canister near the front where the lines go up and over the frame rail? Also, any idea where I can get a replacement for the flexible hose part?
That canister is a receiver/dryer and is made of 'unobtainium' .... just install the original. There is a union in the liquid line just in front of the passenger side rear wheel; just remove the union, cut and reflare and install an inline filter/dryer. Remember freon is a solvent and will clean the system:grin: Actually only one time did the filter/dryer clog to the point of needing change (your first clue will be higher than normal discharge pressures and lower than expected suction pressures and freezing just behind the filter/dryer). Commercial refrigeration still uses the flexible lines...use the old ones if not leaking since you will not find the exact size and will have to make modifications. Classic Air, Vingtage Air are no help on original 55 systems. Willie
